This paper discusses the development of a digital mapping program at the Defense Mapping Agency (DMA). The evolution of a conventional mapping production program from time consuming labor intensive processes into highly interactive and versatile operations is covered. Special emphasis is placed on the rationale for implementation of enhanced hardware and software technologies into the production processes.

The availability of both global and regional elevation datasets acquired by modern remote sensing technologies provides an opportunity to significantly improve the accuracy of stream mapping, especially in remote, hard to reach regions. Stream extraction from digital elevation models (DEMs) is based on computation of flow accumulation, a summary parameter that poses performance and accuracy challenges when applied to large, noisy DEMs generated by remote sensing technologies. Robust handling of...

In order to effectively communicate, man must have a common language. In the conventional or digital cartographic sphere, this axiom is no less true. Symbols form the language of cartography. Ideally, a worldwide standard set of symbols would solve many of the communication problems. But, this ideal solution is not technically feasible. However, within scale families of maps, standard symbology should be sought, especially in computer cartographic applications. This paper addresses the need for...

The performance of image classification techniques as applied to color cartographic maps is compared. These color maps have a lot of graininess due to imperfections in the printing process. This graininess decreases the efficiency of compression techniques. The color maps are classified using the K-means clustering algorithm and vector quantization with neighborhood classification to improve the visual quality and compression ratio.

At present, the preparation of lunar maps re quires the aid of photogrammetric methods. For such mapping as well as for all other kinds of mapping, it is most important to determine the geometrical quality to be expected in planimetry and elevation. Topographic mapping of the earth can be checked with ordinary geodetic methods, but for obvious reasons, the geometrical quality of lunar mapping can be checked in a similar manner only after man has landed on the moon. Therefore, the only...
